I have dealt with SSB before, they are good but you can get better quality off a guy on e-bay. I got my 731 manuals from SSB tractor and i was very happy with them.
As for the U-joints, you need to lift the cab and access it through the blower housing, its not an easy job! but it can be done. If the U-Joints are not oem you may need to pull the engine to access them. The ones i recently got had a different grease nipple location! There should be 3 grease nipples back there.

Thanks Tazza.

I have a copy of the 641/642/643 service manual. They are basically the same machine. I have a 642 which has a Ford Industrial gas engine in it. I believe the 641 is a Deutz air cooled diesel and the 643 is a kubota diesel..maybe its the other way around. If you need something specific, give me a shout and I could scan a few pages for you if you need something short term. Long term, when I get a minute I can make a copy of it for you and send it to you.
I have scaned some parts of it, if you need something specific, let me know. I also have the owners manual electronically if you want it. I could send you that, it at least has the preventative maintenance schedule and some other machine specs that are at interesting.

If you e-mail me, put "643 Bobcat" in the subject line, otherwise I may be delete the e-mail if it from someone I do not know.

Thanks
Bernie
